Essential Electric Supply stocks new and recertified AFCI circuit breakers ready to ship the same day you order, including combination AFCI, plug-on neutral, and legacy panel replacement options.
An arc fault circuit interrupter (AFCI) breaker is a protection device that detects dangerous electrical arcs like abnormal electrical discharges in wiring and connections that standard breakers cannot sense. Where a standard breaker trips on overloads and short circuits, an arc fault circuit breaker trips on arc faults, which are a leading cause of residential electrical fires.
Combination AFCI breakers, the type required by current NEC code in most applications, protect against both parallel arcs (wire-to-wire contact) and series arcs (loose connections or damaged conductors) in a single device.
Under NEC 210.12, AFCI protection is required in bedrooms, living rooms, dining rooms, hallways, closets, and most other habitable rooms in new construction and renovation work. If you’re building new, upgrading a panel, or pulling a permit on a renovation, combination arc fault circuit breakers are the correct type to specify. Applications include residential panels, new construction, and panel upgrade and renovation projects.

Shop Our AFCI Circuit Breakers
We stock new and recertified AFCI circuit breakers from the industry’s most trusted names and model lines, all in one place and ready to ship:
Brands & Series: Square D QO, Square D Homeline, Eaton BR, Eaton CH, Siemens (including plug-on neutral), ABB, GE, and Connecticut Electric ETL-listed replacements for legacy panels.
Arc fault circuit breakers must match both the panel manufacturer and model line. For example, a Square D QO breaker is not interchangeable with a Square D Homeline panel, and plug-on neutral AFCI breakers are not compatible with older panels that lack a dedicated neutral bar. If you’re unsure which breaker is compatible with your panel, contact our 24-hour support team before ordering, and we’ll confirm the right unit for your application.
Every recertified arc fault circuit breaker is tested to OEM specifications before it ships and is backed by our two-year warranty. UL-listed and ETL-listed options are available for both current production panels and legacy panel replacements. If the exact model line you need has been discontinued or is hard to source, our team can identify compatible replacements, including ETL-listed alternatives.
With same-day shipping on in-stock orders placed by 1:30 PM PT, multiple ship points across North America, and 24-hour emergency support, we’re ready when the job can’t wait.

Frequently Asked Questions
What is the difference between an AFCI breaker and a GFCI breaker?
AFCI breakers detect dangerous electrical arcs in wiring and connections that can cause fires. GFCI breakers detect ground faults that can cause electrical shock. Some NEC-required locations call for both types of protection. Combination AFCI/GFCI breakers are available for locations where both are required. See our GFCI circuit breaker collection for GFCI-specific options.
Where are AFCI breakers required by NEC code?
Under NEC 210.12, AFCI protection is required in bedrooms, living rooms, dining rooms, hallways, closets, kitchens, laundry areas, and most other habitable rooms in new construction and renovation work. Requirements vary by jurisdiction and code adoption year. Always confirm with your local authority having jurisdiction (AHJ) before specifying for a permitted project.
What is a plug-on neutral AFCI breaker?
A plug-on neutral arc fault circuit breaker connects directly to the neutral bar in the panel without a separate pigtail wire, simplifying installation and reducing wiring clutter in the enclosure. Plug-on neutral breakers are compatible with panels that have a dedicated neutral bar designed for them, but are not compatible with older panels that lack this feature. Confirm your panel model before ordering, or contact our support team for compatibility help.
Do you offer same-day shipping on AFCI circuit breakers?
Yes. Orders placed by 1:30 PM PT on in-stock units ship the same day via UPS. Free UPS Ground shipping is available on orders over $250 within the continental United States, and expedited after-hours air delivery is available for time-critical situations. With multiple shipping points across North America, most customers receive their parts quickly regardless of location.
Are your recertified AFCI breakers tested before shipping?
Yes. Every recertified AFCI circuit breaker is tested to OEM specifications before leaving our warehouse. Recertified units ship with our two-year warranty, the same coverage applied to new stock, and all orders are backed by our 30-day return policy.
Do you carry AFCI breakers for older or legacy panels?
Yes. We stock ETL-listed arc fault circuit interrupter replacement breakers compatible with legacy panels, such as Federal Pacific Stab-Lok replacements via Connecticut Electric. If you’re sourcing for an older panel and can’t find the exact unit through standard channels, contact our team with your panel model, and we’ll identify a compatible replacement.
